Answer 12

to be safe, what grade are you in?

Answer 13

i am and i did the adding it's just your talking about subtracting a fraction from a whole number and i really really really really at math

Answer 14

i only in 6 th but i'm in home schooling so my teachers don't help me

Answer 15

what numbers do you have so far?

Answer 16

i have 25/8 and it might be wrong but like i said i suck at math

Answer 17

that is right so far.
now, in order to add fractions, the denominators, the number at the bottom, must be equal. Did you know that?

Answer 18

yes

Answer 19

good. so you need to find a number that, if you divide it by 8, you get 5. what number is this?

Answer 20

?

Answer 21

think about it like this.
you are addding 25/8 +5, but you can't do it yet because the denominators are not the same.
so what can you do to 5 to let it have a denominator of 8?

Answer 22

you can divide it by 40

Answer 23

close. do you mean like this 5/40?

Answer 24

actually i was thinking the other way around 40/5

Answer 25

right!:) good job.

ok. i made a mistake earlier when I said you are adding 25/8 +5. really, you are doing this:
5-25/8.

Can you take it from here?

Answer 26

Answer 27

ok. I'll tell you if your answer is right once you tell me what you get.

Answer 28
